Application med ay 14,

To all whomtmay consom.'

Be it known that we, Looms E. ADAMS and s C. Prox, both citizens of the United States, and residents of Munising, in the county have invented a new and Improved Snowplow, of which the following is a full, clear, and exact'description.

This invention relates to snow plows and has. for an ob'ect to provide an improved construction w ich may be applied to trucks, tractors or en7 suitable motor vehicle.

Another object in view is to provide a snow plow structure which may be connected to a motor vehicle and arranged and supported principally by traction members enga 'ng the ground while connected to the ve 'cle in such e. manner as to be pushed readily along.

A'stiil further object of the invention is to provide an improved snow plow structure which includes a V-Shaped plow member attachable to the front of the vehicle, auxiliary plow members or rutters nrran ed in front othc wheels of the vehicle and etlecting wings arranged in back ot' the V-shaped plow structure whereby a comparatively wide swath is cleaned at one operation.

In the accompanying drawings- Figure l is aside view of a truck with an embodiment of the invention applied thereto.

Figure 2 is atop plan vieur of the structure shown in Figure 1.

Figure 3 is a top plan view of one of the side wings and actuatin members therefor.

Figure 4 is a sectionalgview through Figure 3 on MucA-4.

'Figure 5 is an enlarged detail sectional view through Figure '2 on line 5-5.

Figure 6 is an enlarged fragmentary rear view of one of the elevating screws and associated parts embodying certain features of the invention.

Figure 7 is an edge view of the structure shown in Figure 6.

Referrino to the accompanying drawings by miniera, 1 indicates a motor vehicle or truck of any desired kind to which the various parts of the plow are connected. The truck shown. in the drawing is provided with a box 2 which is associated with a hoist or elevating mechanism whereby the box may be dumped. When a truck of this of Alger and State of Michigan,`

structure must be used for holdiny and drawing in on the cables 3 which cab es areV used to brace and also tilt the front plow.

As lshown in Figures 1 and 2 the front plow is provided with moldboords 4 and 5 which are twisted somewhat to give the dethesnow, said moldb'oards being connected together at 6 for forming substantially a V- aped structure. Suitable bracing member 7 are used for bracing the moldboards, said bracing members including a central bracing member 8 which acts 1n the double capacity of bracing members and ineens for 4connecting the runner 9 to the plow.

As shown in Figure 5, the runner 9 is a short runner rounded at the front and provided with one or more. metal plates 10 to which a bolt or rod 11 is pivotally connected at 12. The rod 11 extends u wardly through a bar 13 and through tEe beam 8 so that the sprin 14 muy be positioned around the end t ereof of the nut 15 used for producing proper tension on the spring for holding the runner 9 against the bur 13. The bar i3 if: a substantially U- .shaped bar preferably with a Het section and with the ends connected by bolts, screws or otherwise to the plow. This construction permits the plow to be supported by the runner 9, while allowing the runner a. free Swingin movement resisted by the s ring 14. ost of the weight of the p ow is supported by this runner` and the runner moves along en the ground or a lower layer of snow so that it conforms to the nature of the rond and, consequently, holds the lower edge of the rnoldbonrds 4 and 5 a short Adistance 'from the ground. At the rear the frame or bracing hor 7 is formed with a pair of uprights or posts 16 and 17 connected by a transverseY bar 18 at the bottom and a transverse bar 19 approximately half way between the bottom and the top. These bars are adapted to receive the central bracing beam t? and thc other parts of the frame 7 so as to present a form of rigid structure for supporting the mold boards l and 5. Connected with euch of the posts 16 and 17 is a fitting 20 to which the beam 21 is pivotally connected, seid beam currying an auxiliary or wheel plow 22 or ruiter as it is sometimes called. This arrangement causes the snow tobe cleaned oli' directly in front of the wheels of the vehicle whereby a good contact with the surface of the road may be secured. Ordinarily. the pivotal connection as just dcribed wili be suflicient but if desired, a ro e or other means could be connected with t e beam 21 so as to raise the rutter 22 if desired, as for instance, when moving'rapidly to a place where snow is to be removed. v

A pair of braces 23 are connected to the front of the l osts 16 and 17 and to the front end of e low so that whenever the cables 3 are pulle the front of the plow may be tilted upwardly to an inoperative position. In order to accomplish this, the posts or uprghts 1G and 17 are pivotally mounted on the cross beam 24 which is rigidly secured to the chassis of the automobi e by Suitable stra is 25. A pin 26 is carried by each end of t e bar '(Figs. 6 and 7) and said in accommodates the bfurcated ends 27 o a fitting 28. It will be noted that the bifurcated'ends 27 slidably [it against a guiding bracket 29 so that when the respective p arts move they are guided. An elevatin screw 30 is threaded into each of the ttin s 2B and are supported by bracket 31 rigid y se cui-cd to the respective u rights 16 and 17. A bevel gear 32 is rigid y secured to each of the elevating screws 30 and mesh with the respective gears 83 carried by the conner-ting rod 34, which rod is Provided with a hand wheel 35. The brackets 31 are carried hy the posts 16 and 17 so that when the hand wheel 35 is rotated the osts will he raised or lowered in respect to t e bar 24 while at the same time the entire glow is allowed to pivot on the pins 26. y this arrangement, either the rearor the front of the plow may he elevated independently to secure the desired adjustment and the entire plow may be swung` upwardly out of the way wheneverdesired, as for instance when moving rapidly from one place o operation to another. It will be noted that the plow structure at the front of the vehicle enters and spreads the snow approximately the width of the vehicle but in order to prevent the snow from falllng back and also to widen the path, wings 36 and 37 are provided, said wings being arranged preferably on the sides of the vehicle between thc front and rear wheels. These wingsA are identical so that the description of one will apply to both. The wingr 37 is provided with a moldboard 38 of the desired curvature and is supplied with suitable bracing liars 3i) which are pivotally connected at 40 tr) suitable brackets 41 whereby hinge struc-turcs are produced as shown in Figure fl. The brackets 4l are rigidly secured to a Iilocl; i2 which block may be wood or any desired material and which is provided wit beneath the Hanges 43 and 44 extending ly secured to Ithe block 42 and oo-acts with the liftin screw 452 rotatably carried by the frame 4 and govided with a hand wheel 53 (Fig. 4). y actua-ting the hand wheel 53, the wings 37 may be raised or lowered without disturbing the braces 39 or any other part of the device. In order to swing the moldboard inwardly or outwardly on the hinge structure produced b members 40 and 41, a pivotal-1y mounted link 54 iS pivotally connected to the moldboard 38 at 55, said link passing loosel through a post 56 carryin a set screw 5 The moldboard is move pivotally to the desired position and the Vlink 54 slides in post 56. VSaid screw 57 is then screwed down tight and the link and associated parts are thereby rigidly clamped against further movement.
